Some of the information on this page is obsolete. Please click here to view up to date part numbers, specifications and prices for small block Chevrolet dome pistons from Ross. The information on this page is being left online as a reference for people who may have some of the older part numbers, or find them on ebay, at swap meets, etc.

ROSS includes forced pin oilers and double spirolox on all of our stocking pistons. Pistons are balanced to plus or minus 2.5 grams throughout the set. You can buy replacement pistons one at a time as needed. Our valve pockets are designed to handle most camshaft applications. Our skirt design allows the pistons to work properly under intense heat and tremendous side loads without scuffing or splitting cylinder walls. Most normally aspirated pistons are designed to operate at .004 piston skirt to cylinder wall clearance. All ROSS stocking pistons include aircraft quality pins that are heat treated and end ground to work in full floated or press fit applications.
